dsetool list_subranges
Lists the subranges of data in a keyspace to describe a token range by a number of smaller subranges.
Lists the subranges of data in a keyspace by dividing a token range into a number of smaller subranges. Useful when the specified range is contained in the target node's primary range.

| UPPERCASE | Literal keyword. |
| Lowercase | Not literal. |
Italics |
Variable value. Replace with a valid option or user-defined value. |
[ ] |
Optional. Square brackets ( [ ] ) surround optional command

'Literal string' |
Single quotation ( ' ) marks must surround literal strings in

{ key:value } |
Map collection. Braces ( { } ) enclose map collections or key
value pairs. A colon separates the key and the value. |
<datatype1,datatype2> |
Set, list, map, or tuple. Angle brackets ( < > ) enclose
data types in a set, list, map, or tuple. Separate the data types with a comma.

cql_statement; |
End CQL statement. A semicolon ( ; ) terminates all CQL
statements. |
[ -- ] |
Separate the command line options from the command arguments with two hyphens (
-- ). This syntax is useful when arguments might be mistaken for
command line options. |
' <schema> ... </schema>

Search CQL only: Single quotation marks ( ' ) surround an entire
XML schema declaration. |
@xml_entity='xml_entity_type' |
Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files. |
